Gahow Wang b17b213575 Tear down the engine on SIGTERM instead of orphaning it ...

Killing `study tune` with a default SIGTERM skipped the finally blocks, leaving the
vLLM engine and its EngineCore workers (which inherit the AITUNER_* marker env) alive
on the GPUs — twice leaking GPU memory that needed a root reset. Install a SIGTERM
handler in run_trial that raises KeyboardInterrupt so _terminate_process_tree runs,
ignore SIGTERM during teardown so a second signal can't re-orphan it, and restore the
prior handler afterward. Main-thread-guarded; unit-tested.
